Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace gas cabinet components, in particular to a circulating oil supply device for a blast furnace gas cabinet. Background Technique

[0002] A blast furnace gas cabinet is a device used in a steel mill to store and regulate blast furnace gas. The circulating oil supply device of the blast furnace gas cabinet is mainly responsible for transporting liquid fuels (such as kerosene, diesel, etc.) to each use point to ensure the normal operation of the gas cabinet.

[0003] The existing circulating oil supply devices for blast furnace gas cabinets still have the following problems when in use: when the circulating oil supply device conducts the liquid fuel circulation supply work for the blast furnace gas cabinet, it often needs to filter the circulating liquid fuel, and thus is equipped with a filter to filter impurities in the liquid fuel to prevent impurities from entering the system and causing equipment wear or blockage. However, since most of the filters for circulating oil are designed with a pipe connection structure, when replacing the filter medium inside, it often needs to cooperate with a wrench to remove the filter before the filter medium inside can be replaced.
